' Application February 25, 1931, Serial No. 518,044 Renewed September 6.1933 19 Claims., (Cl. 271-63) This invention relates to printingmachines, particularly large newspaper printing machines and folders.

The principal object. of the invention is to provide a device whichwillindicate at the folder when a, splice is being made; and to providemeans for setting askew the papers containing this splice on thedelivery so that these papers may be recognized and lifted out,'eitherin the press room or the delivery room. The invention also involves theprovision of these features in a simple and inexpensive construction.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 isan end view of a folder with a throwout device thereon constructed inaccordance with this invention; I

Fig. 2 is a front view of part of the same, taken in the direction ofthe arrow 2 in Fig. 1;

Fig. 3 is a horizontal sectional view taken on the line 3-3 of Fig.- 2;

Fig. 4 is a plan of the delivery showing several papers thrown out inaccordance with this invention, and,

Fig. 5 is a wiring diagram showing how the throw-out device is operatedin conjunction with the pasting mechanism.

When the expiring web is pasted to a new web roll oneor .more of thepapers produced are spoiled because of the fact that the two webs arepasted together. These papers are not intended to be sold and they haveto .be picked out and thrown away.

iThis invention provides an automatic means for identifying these papersso that no search will have to be made for them and for displacing themon the delivery belts so that they can be taken out very easily.

Of course the running web W and the web roll Ill are associated with apasting device which involves a solenoid l2 located in an electric line.

In series with this solenoid are a pair of contacts i 3 which areadapted to be closed by a switch 14 operated by a cam l5 rotating withthe web roll. The roll in, after it gets into the proper position, isstarted into rotation in the proper direction and once during eachrotationthe cam I5 closes the contacts l3 and M. This occurs when thepasted spot on the roll in reaches the roper position for attachment tothe web W.

I have shown the pasting device in a form involving a brush 16 forfinally bringing the parts 55, together. It will'be understood that thisis not all the mechanism involved and that the particular pastingmechanism shown is not essential, but I have merely illustrated theseparts to show how one form of pasting mechanism can be made to cooperatewith the rest of the machine. This invention is applicable to thoseconstructions in. which the roll l0 rotates'only through one completerevolution.

When the contacts l3 and M are closed, which is only for a short time, acurrent will be set up in this electric line and a solenoid llenergized.

The result of this is to pull in a toe [8. It will be understood thatthis toe is pulled in only when the paster is being operated.

On the folder M is a folding and cutting couple 42- 43 to receive theweb from the folder rolls 44 and to cut the web into the desired foldedproduct, as newspapers. The folding couple can be formed in any desiredway, as for example, in

my prior Patent 1,937,456, patented November 28,

1933, to cut'the web with such cutters 45 as are shown therein. Thisconstitutes means for converting the web into newspapers or signatures.

A shaft 20 is mounted on the frame of the folder ll and connected withthe press to run 'in proportion to the speed of the press, so thatwhether the press is running slowly or rapidly this shaft will rotate insynchronism therewith. On this shaft is a worm 2| operating a worm wheel22 on a shaft. 23. This shaft is rotatably carried in brackets 24attached to the frame of the machine and has pinned to it a frictiondisc 25. Also loosely mounted on it is a cylinder 26 which is pressedagainst. the friction disc by a spring 21, washer 28, and nuts 29; thuswhen the 35 shaft 23-rotates the cylinder 26 tends to rotate" also. Thiscylinder carries a projection 30 which abuts against the toe l8 operatedby the solenoid I'I. Normally these parts are in the position shown-inFig. 3. Energizing of the solenoid i'l pulls the toe iii to the leftin'that figure, thereby freeing the projection 30 and allowing the cylthepress.

when the cylinder 26 has rotated through a predetermined arc, whichisgoverned by the distance from the reel to the delivery bucket, aproinder 26. to rotate in synchronism with the shaft 23, that, is, indirect proportion .to the speedof lever 31 and pulls the outer end 38 ofthis lever down. This end 38 constitutes a kicker located delivery thathave at one side of the delivery belts 30, and when'it comes down itsets a few papers askew as they travel along, as shown in Fig. 4 on thedelivery 3!. The length of the cam 3| determines 'the duration of theactivity of the kicker II.

when the cam II passes beyond the switch roller 32 the solenoid 34 isdeenergized and a spring 40 returns the kicker to its inactive positionshown in full lines in Pig. 1. The cylinder It continues its rotationuntil the projection ill again contacts with the toe II. This toe hasbeen returned to operative position by the fact that the cam I! haspassed beyond the switch I4. The light 35 or bell can be placedconspicuously on the folder or in any other desired position and isconnected up in parallel with the solenoid 34, when used.

It will be understood, of course, that the time taken for the papers topass from the paster to the folding machine 4| must be determined andthe cam 3| set accordingly; sothat when the pasted paper or papers getto the delivery'belts is the kicker will act to throw those particularpapers out and also one or two more papers ordinarily It is beunderstood that-without departing from the scope of this inventionpapers might be diverted out of the path of the regular delivery 30 bya. device of this description as stated, or that the light or bell orboth may be placed at the folder or in the delivery room fornotification of the arrival of the pasted papers when, withoutdisplacement, they can be taken off by hand.

-Either of these things can be used alone, but it is desirable to usethemtogether.

It will be seen that as the operation of the cylinder 26 is proportionalto the press speed,

the length of time that the switch 33 is closed is proportional to thespeed of the press. Whether the press is running fast or slow, the samenumber of papers,will be set askew in the delivery. In this way a simpleand accurate device is pro- .vided for locating and displacing thepapers, or

both, which are spoiled by pasting.
